Oktoberfest Beer-Braised Brat Smash Burger with Bavarian Mustard Sauce
Ingredients:
- 1 lb ground bratwurst
- 4 burger buns
- 1 bottle of Oktoberfest beer
- 1 onion, thinly sliced
- 1/4 cup Bavarian mustard
- 1/4 cup mayonnaise
- 1 tbsp butter
- Salt and pepper, to taste
- 4 slices of Swiss cheese
- Pickles, for serving
Instructions:
Start by preheating a skillet over medium-high heat. Form the ground bratwurst into 4 patties and season with salt and pepper. Place the patties in the skillet and cook for about 4-5 minutes per side, until browned and cooked through. Remove the patties from the skillet and set aside. In the same skillet, add the sliced onions and cook until caramelized. Pour in the Oktoberfest beer and let it simmer for a few minutes until slightly reduced. Return the brat patties to the skillet and let them braise in the beer mixture for another 5 minutes. While the patties are braising, mix the Bavarian mustard and mayonnaise in a small bowl. Toast the burger buns in a separate skillet with butter until golden brown. Place a slice of Swiss cheese on each brat patty and cover the skillet until the cheese is melted. To assemble the burgers, spread the Bavarian mustard sauce on the bottom half of each bun, then place a brat patty with melted cheese on top. Top with caramelized onions and pickles. Serve hot and enjoy this delicious Oktoberfest-inspired smash burger!
